What Is SCADA and Why Are Texas Energy Companies Hiring IT Workers to Protect It?

SCADA systems run Texas’s energy infrastructure — and they’re increasingly targeted by cyberattacks. Here’s what IT workers need to know about this growing job market.

If you’ve been looking at IT job postings in Houston and noticing terms like SCADA, ICS, OT security, and industrial control systems appearing with increasing frequency, you’re not seeing niche roles. You’re seeing the fastest-growing cybersecurity specialization in Texas — and one of the highest-paying ones. Here’s the context that makes those postings make sense.

What SCADA is

SCADA — Supervisory Control and Data Acquisition — is the category of control system architecture that monitors and controls industrial infrastructure. In Texas, that means oil pipelines, natural gas distribution networks, refinery operations, wind farms, and the ERCOT power grid management systems. A SCADA system ties physical sensors and actuators to a central control interface: the operator can see current pipeline pressure on a dashboard and open or close valves remotely.

These systems were built for reliability, not security. Many were designed before the internet existed as an enterprise technology, and they ran in isolation from everything else for decades. That isolation — the “air gap” between industrial systems and corporate networks — was the security model. Physical access was the perimeter.

Why that model is breaking down

Energy companies have spent the past decade connecting SCADA systems to corporate IT networks for remote monitoring, predictive maintenance, and operational efficiency. The efficiency gains are genuine and significant. So is the attack surface that didn’t exist before. SCADA systems that were never designed to face network-based attacks are now reachable from the internet, running unpatched operating systems, using industrial protocols with no built-in authentication.

When a ransomware attack hits a retail company, they lose sales revenue. When it hits a pipeline control system — as Colonial Pipeline demonstrated in 2021 — they lose the ability to safely move fuel across the country for six days. The stakes are not comparable, and neither are the salaries for the people tasked with preventing it.

What the job market looks like

OT Security Analyst: $85,000–$115,000 entry-to-mid. ICS Security Engineer: $100,000–$140,000. IT/OT Convergence Specialist: $95,000–$130,000. These are not senior-only roles. The demand is creating entry-to-mid positions because there simply aren’t enough experienced OT security professionals to fill the need, and companies are willing to develop candidates with the right foundational knowledge.

How to build toward it from an IT starting point

The path is: CompTIA A+, Network+, Security+ — then two to three years of IT or IT security experience — then GICSP (Global Industrial Cyber Security Professional) certification and OT-specific knowledge. Nobody goes directly from zero to OT security. The foundation is the same as any cybersecurity career; the specialization layer comes after.

The foundation is what the Infotech Academy Pre-Apprenticeship Program covers. The OT specialization is where you go from there. If Houston’s energy sector interests you as a long-term target, you’re already on the right path if you’re starting with CompTIA certifications — those are the beginning of the trajectory, not a detour from it.
